Be it known that l, SAMUEL JV. FIsH, a citizen of the United States, residing at Plainfield, in the county 01": Union and State and useitrd improvements in Looking Dcvices for Safe and Vault Doors, of which the following is a specification Thepresent improvement relates to safe or vault doors, and more particularly to the boltingmechanism there-oi, the object of the invention being to provide improved means foiyoperating such bolting mechanism, the present application being a division of my contemporaneously pending application Serial No. 530,9-13, filed December 2, 1909, now Patent lo. 997,778 dated July 11, 1911.

In the drawings accompanying and forming part of this specification, Figure -1 is a rear view of a part of a vault door having part of the bolting mechanism broken away; Fig, :2 is partly a side and partly a sectional view 'of this improved door and its bolting mechanism; 3 is, a detail View illustrattion bi the means for protracting and review of the means for operating the bolts.

Similar characters of reference indicate corresponding parts tlroughout the figures or the drawings. 7

It is desirable in practice, especially in large vault doors, which usually weigh many tons, to so support the bolting mechanism that the supporting means therefor maybe separate and independent of the door proper but so connected therewith that to ailintents and purposes the door and its bolting mechanism are aunitary structure, and-this made of un'machmeable metal, since in such cases, when the door is itself provided with bolt openings the casting must not only be unusually heavy and massive, but the heat treatment thereof is difiicult. In the present improvement, in order to .do away with thesedisadvantages, the door is made up of a pair of members, anouter or body member andan inner or bolt supporting member, the

latter of which may be made of some: suit-i,

able steel less difficult to machine, whereby 1- 0 the outer member may be readily made .or

unmachmeable metal and treated while.

the inner member, as stated, may be made of a different steel-and of a steel which can be readily machined. The foregoing, however, constitutes broaclly the subjectrmatter of my contemporaneously pending application hereinbefore referred to. The present 1mprovement,. however, 7 particularly relates to the locking devices for the safe or vault doors.

The door 2 in the form shown comprises an outer member 3 having preferably a rearwardly extending flange 4 provided around the same with suitable lugs 5. The inner or bolt carrying member 6 may comprise an annular ring 7"having lugs 8 adapted to cooperate with the lugs. of the outer memher 3 and 'so be interlocked therewith, suitable keys Q'b'eing provided for preventing the separation of the two members of the door when once they'are interlocked, the detachment of these keys being prevented by an annular ring or plate 9- secured to the inner member of the door. The annular member 7 is provided with suitable bolt openings 10 and 11 carried by projections 12 and 13 for the reception of the bolts. Secured to this annular member 7 for sup porting the bolt opratihg means and the time lock and other mechanism usually used in vault dbors,-is a diskl a By reason of this construction it will be observed that the bolt supporting member 7 maybe made of a different metal from that of which the main portion of the door is made, and of a metal which can be readily ma chined, the two membersbeinginterlockedby a rotary v'motio-nof one relatively to the other through the medium of the lugs, and when so interlocked keyed or otherwise held together. In practice the vault doors may be provided Wlth a protecting plate 20 between the body door'a-nd the inner bolt sup- 9 5 porting-member 7 L For operating the'bolts suitable gearing is provided, this 'being automatically operated or otherwisepas found most desirable in practice. This gearing in the present in'-- stance comprises a ringv gear ;30 meshing: with a series of segmental gearsior segments 31, one connected withv each bolt, and for; this purpose each segment 31 ispivotally connected by an arm or crank 32 with its belt,whereby, on rotating the ring gear, the

segments will be operated to eitherwithdraw or protract the bolts, each segment and its connected crank arm thus forming a toggle joint, so that when the bolts are protracted the pivotal connections of the crank arm of each bolt are in alinement, and therefore in a dead-center position, so that it is impos sible toforce in or retract the bolts except by rotating the operating gear 80.

By reason of the present improvement I amv able not only to provide an improved operating means for the bolts, but also an improved means for supporting and secur ing the bolts to the door, thus obviating the necessity of having the-bolt supporting p0rtlOIl of the door and the door proper made as a single massive casting, and also obviating the necessity of making the entire structure of one metal. F

From the foregoing it will be observed that the door comprises a main door memher and an inner member which constitutes both a door and. a bo-dylocking member, since it has on its front side means for interlocking it with the main door and on its rear side means for locking or securing the main door to the safe or vault body, and therefore it will be herein designated as a door and body locking member, since it constitutes the means for securing the main doorto thebody of the safe or vault segmental gears to protract and retract the comprising a plurality ofslidingbolts, a

crank arm for each bolt, a pivot bolt connecting each arm with its bolt, a segmental gear pivotally connected to'eachof said crank arms, and means for operating said segmental gears to protract and retract the bolts. i

a 3. A locking device for safe or vault doors comprising a plurality of sliding bolts, a

crank arm for each bolt, a pi'l ot bolt vconnecting each arm with its bolt, a segmental gear plvotally connected to each of said crankarms, and means for operating said bolts and comprising a rotatable ring gear. Signed at New York, N. Y., this 15th day.
